Abstract
New and useful methods of producing stabilized enzyme antibody conjugates are disclosed which are particularly useful in forming multi-layer immunoassay test devices. In particular, the invention concerns the formation of a manganese ion and enzyme-antibody conjugate in aqueous solution and drying the solution to produce a dry stabilized enzyme-antibody conjugate. Further, this stabilized enzyme-antibody conjugate can be formed on a continuous web and dried in a heat tunnel. This continuous manufacturing process allows for the more efficient production of multi-layer test strips.
